SPECIFICATION forming part of Letters Patent No. 255,157, dated March21, 1882.

Application filed December 29, 1881. (N0 model.)

To all whom it may concern:

Be it known that I, JACOB FoosE, a citizen of the United States,residing at Lancaster, in the county of Lancaster and State ofPennsy1vania,have invented certain Improvements in Steamers, of whichthe following is a specification.

My invention relates to portable devices for steaming tobacco and feed,heating rooms, boiling water, and for use for producing steam for anyculinary or household purpose; and the objects of my improvements are,first, to prevent the passage of the water from the boiler into thefeed-pipes, and, second, to firmly support the boiler and heater. Iattain these objects by the mechanism illustrated in the accompanyingdrawings, in which Figure l is a side view of my steamer, with portionsof the boiler and heater cut away in order to show the internalarrangement of the same; Fig. 2, a top view of the watercheck, and Fig.3 a top view, through the section an, of the heater showing theheatingchamber and grate.

Similarletters refer to similar parts throughout the several views.

My device consists of a boiler. B, and heating apparatus A. The top ofthe boiler is slightly concave, and has a discharge cone or dome, C,(from which the feed-pipe is supplied,) in its center. Beneath the domeO, and closing the opening of the same into the boiler B, is a circularconcave water-check, D. The bottom of'this check D is steam-tight, butthe perimeter has two valves, a, opposite each other, which workinwardly, each having a spring, 8, to keep it closed unless acted uponby the escaping steam. The top 1) of the check is perforated withopenings to allow the passage of steam into and through the dome (J,from which it passes into the feed-pipe P, supplied with a stop-cock, S.In this arrangement water is prevented from escaping from the boilerintothe pipes by the water-check, the perforated top of the check and thecone shape of the domeO freein gthe steam from any water which may haveaccompanied its passage through the valves.

The boiler is supported by the annular base E, of the diameter of andsecured to the boiler at its lower end. An expansion-foot, F, secured tothe center of the under side of the bottom of the boiler, extends towithin a short distance of the floor, and prevents too great depressionof the boiler-bottom by the generation of steam. The annular baseaffords a firm support for the boiler, preventing the jar incidental tothe passage of water between the boiler and heating-chamber yet to bementioned, and at thesame time protects theheated' bottom of the boilerfrom the passage of cold air under the same, while the expansion-foot,being shorter than the base E, supports the center of the boiler, whendepressed by the pressureofthe steam, withoutbecominga pivot about whichthe steamer might rock, the difference in length between the foot andbase being such as to compensate for the depression of the bottom causedby a working head of steam.

The tire-box G of the stove A is surrounded by a water-heating chamber,I, connected with the boiler by two pipes, O and O. The first pipe, 0,connects the bottom of the boiler with the lower part of theheating-chamber, and the second, 0, the top of said heating-chamber withthe upper part of the boiler. The use of these two pipes permits thepassage of water of different temperatures between the boiler andchamber by means of different pipes, facilitating the heating of thewater, and consequently the making of steam. chamber has a spigot, I),attached to it.

The side of the stove toward the boiler is upheld by the pipes O andO,and on the other by one leg, 9. The leg 9 rests in the ash-pan, andserves as a pivot about which the ash-pan is revolved in turning it fromunder the stove to free it from ashes. The shifting and drawing grate his held in place by lugs Z.

The boiler is supplied with water through the feeder H, which extendsfrom the top thereof down to the bottom, the lower end curving so as tothrow the water into the boiler laterally. It also has attached anescape-pipe, f, connected with the safety-valve a, and a whistle, w,which may be detached, if necessary, to make any other connect-ion inits place, or form a simple blow-oft and-a watere'e The heating- Thestove is a self-feeder, having a resertop and valves 11, in combinationwithaboiler, voir, 1', for fuel. The boiler and base are built B, anddome O, substantially as and for the of heavy galvanized tank-iron, andthe conpurpose specified. necting-pipes and chamber 1 of heavy copper 2.Inasteamer, the combination of the boiler 15 covered with galvanizediron. B, annular base E, and the expansion-foot F,

The dome 0 may be shaped differently from as and for the purpose setforth. that described, as I do not limit myself to that precise form.JACOB FOObE' WhatI claim as my invention, and desire to Witnesses: 1osecure by Letters Patent, is WM.
